Answer 6

DNA stands for deoxyribonucleic acid. It is the genetic material. It is responsible for heredity. It consists of bases, a sugar and a phosphate group. The DNA is double-stranded. The strands are complementary to each other and run in anti-parallel directions. The DNA molecule is twisted in a helical structure (refer to the picture @evergirl has posted). @alexxis has referred to stairs which is true! The stairs are the result of the hydrogen bonds between the bases of the two strands :)
